Abstract:
A memory system may include: a memory device including a plurality of memory blocks; and a controller suitable for managing the memory blocks as a plurality of super memory blocks by grouping them in a type corresponding to a predetermined condition, managing a bad block pool of the form of bitmaps and indexes by setting super memory blocks among the super memory blocks, in each of which one or more bad memory blocks are included, as bad super memory blocks, and managing regenerated super memory blocks by checking, through the bad block pool, normal memory blocks included in the respective bad super memory blocks and then performing grouping in the type corresponding to the predetermined condition.
